"King Comics" anthologized more than a dozen King Features Syndicate newspaper strips into a 64 page comic book. It was a Sunday comics manga for a dime. I purchased this issue at Comics Dungeon in Seattle for $3 last week.
I've begun an ongoing series at HiLobrow that pairs 4CP images with the full panels or pages from which they were cropped. Get a sense of scale, see how cool or lame the orginal contexts were, and be inspired to try this at home, kids!
